g Turn the drum unit over by holding the
green handles. Make sure that the drum
unit gears (1) are on the left hand side.
h Note the following information from the
drum dot check sheet:
 Dot colour
For example, a mark on the cyan
drum would produce a cyan dot on
the check sheet.
 Dot location
Note which of the printed columns
the dot appears in.
i On the problem colour drum, use the
numbered markers next to the drum
roller to find the mark. For example, a
cyan dot in column 2 on the check sheet
would mean that there is a mark on the
cyan drum in the "2" region.
